Improvement in straw-cutters



'tant 6- Q @anni @effi SAMUEL F. ES'IEIJL, OF. RICHMOND, INDIA-NA.Letters Patent No. 88,023, (lated March 23, 1869.

To all whom it mafy concern:

Be it known that I, SAMUEL F. EsTELL, of Rich mond, in the county ofWayne, and State of Indiana, have invented certain new and usefulImprovements in Straw- `-Gutters; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying' drawings, making a part of this specification.

'lhelnature of myinvention relates to a novel method of actuating thefeed-rollers; and also to the mode of attachingA and operating theknife, whereby it receives a combined rotary and reciprocatingr motion.

To enable others skilled in the art to make and use my invention, Iwillproceed to describe the same, with reference to the drawings, in which-Figure l is a perspective view of my improved strawcutter, and

Figure 2 is an end elevation of the same.

The box is made in the usual foi'rn, and is provided with feed-rollers,C D, to which latter are attached the ratchet-wheels E F. y

The journals of the lower feed-roller, G, revolve in stationary boxes,while those of the upper roller, D,

revolve in vertical slots in the side-boards A A', and

are held in position by means of pins, L L', placed u-pright in theslots, and impinging. upon the springs S S.

The shaft H is provided with a balance-wheel, W, and crank, Y, to whichlatter, one end of the knife B is attached, the other end being pivotedto the swinging arm Q. A v

By means of this mode of attachment, any point in the cutting-pant ofthe knife will, in operation, describe an ellipse, this motion being dueto the combined rotary and reciprocating motion which it receives.

The knife is kept in contact with the'brace P by the crank Y and guardX.

The feed-rollers are actuated by means of a carnwheel, N, placed uponthe shaft H, and acting upona pivoted bar, G, to the extremities ofwhich are attached lpawls, I J, that engage with the ratchet-wheels E F.

The cam-wheelN is adjusted to move between two projections on thepivoted bar G, in one of which is a set-screw, R, whereby the space inwhich the camwheel moves may be widened or diminished at pleasure,thereby regulating the length of the feed.

The bar G is pivoted at its central point, so that the feed-rollers aremoved through equal arcs by each revolution of the cam.

Having thus fully described my said invention,

What I claim, and desire to secure by Letters Patent isl. The cam-wheelN, pivoted bar G, and pawls I J, when combined and operatedsubstantially in the manner and for the purpose set forth.

In combination with the cam-Wheel N, and pivoted bar G, the set-screwIt, for regulating the feed, substantially as set forth.

3. The crank Y, knife B, and swinging arm Q, when combined and operatedsubstantially as described.

SAMUEL F. ESTIBLL.
